Great choice, Jac. Remember, quitting is done one day at a time. Post roll, keep your word all day, then repeat. Click on the "Welcome Center" link at the top if you haven't already. Read everything, posting roll, etc. PM me if you have any questions. A moderator will probably be in contact with you shortly. Check your "inbox" (upper left corner).
Also, quitting forever is really hard...so don't think about it. Don't even think about tomorrow, next week, next year. We'll worry about them when they get here. Just focus on today...this five minutes. After you post roll and give your word, fight with everything you've got to make it through today. And repeat.
Before discovering this site, I "tried" to quit a bunch of times. Always failed. The ONLY thing I have done differently this time is to use this site. Read everything you can. There is a ton of wisdom. The better you understand addiction, the better you will be able to fight it.
And, embrace the suck!!! That is the feeling of your body recovering. You GET to go through it...it is a privilege that you earn one day at a time. Stay strong, stay quit and live free.
